In today’s regulated environment, a vendor audit is more than just a compliance obligation—it's a critical part of protecting your product, patients, and company reputation.

Too often, audits become checklist exercises instead of value-driven assessments. At GXP Auditing & Consulting Services, we believe effective vendor audits uncover real risks, validate controls, and support strong partnerships—not just paper compliance.

🚨 Common Vendor Audit Pitfalls:

✅ Over-reliance on pre-approved checklists
✅ Inadequate review of data integrity controls
✅ Lack of clarity on critical-to-quality (CTQ) processes
✅ Not aligning audit depth with risk level of the product/process
✅ Poor follow-up on CAPAs after audit closure

✅ What Sets a GREAT Audit Apart?

✔️ Risk-Based Planning: Not all vendors need the same level of scrutiny. Prioritize based on the criticality of the services, historical performance, and regulatory impact.

✔️ Process-Focused Review: Go beyond SOPs—evaluate how procedures are applied on the floor. Observe, ask, and confirm.

✔️ Data Integrity Review: Whether it's batch records, lab results, or electronic systems—data integrity must align with ALCOA+ principles.

✔️ Audit-Ready Culture: Strong vendors welcome audits. They view findings as opportunities to improve—not just something to “pass.”

✔️ Actionable CAPAs: Post-audit follow-up is everything. Strong audits produce clear, prioritized, and trackable CAPAs that reduce risk long-term.

💡 Pro Tip:

An effective audit also builds relationships. When conducted professionally, audits help vendors improve and demonstrate your company’s commitment to quality—not just compliance.
